SPECIFICATION forming part of Letters Patent No. 752,831, dated February' 23, 1904.

Application filed May 6, 1903. Serin NQ. 155,943. f (nu model.)

a sash in which the several' parts thereof areeasily assembled or taken apart, one which may be made to have the same appearance onu both sides of the sash, and one in which the putty used will have lout a small portion thereof exposed to the weather.

The invention consists of the novel construction, arrangement, and combination of parts, as will be fully described hereinafter and fully set forth in the claims annexed hereto and forming a part of this specification, and the inven-` tion is carried out substantially as illustrated on the accompanying drawings, which also form an essential part of this specification, and

.whereon like characters of reference refer to like parts wherever they occur on the different parts of the drawings.

On the drawings, Figure 1 represents a side elevation of a portion of a window-sash having a plurality of panes of glass and provided with my improvements. Fig. 2 represents a section on the lineA B in Fig. l enlarged and showing the construction of the joint between two or more muntins. Fig. 3 represents a section on the line O D in Fig. l enlarged and showing the muntins as separated longitudinally into two pieces. Fig. 4 represents a section on the line E F in Fig.` 1 enlarged and showing the construction of the joint between a muntin and the outer portion or frame of the sash. Fig. 5 represents aview similar to that shown in Fig. 2, but showing aslightly-diferent arrangement of the device. Fig. 6 represents a view similar to that shown in Fig. 2, but showing still another arrangement of the device. Fig. 7 represents a view similar to that shown in Fig. 4, but showing a slightlydifferent arrangement of the device.

The outer portion l of the sash may be made hollow or tubular, as shown in Fig. 4, or it may be made solid, as shown in Fig. 7, and

the joints at the corners between the several pieces which form the outer portion may be made in any desired manner, as the construction of the same forms no part of my present invention.` The muntins may be made solid, as the muntins 2 in Figs. 6 and 7, or hollow and' tubular, as .the muntins 3 in Fig. 5, or they may be made in two parts 4 and 5, joined together longitudinally and forming a hollow tubular muntin, as shown in Fig. 3, as is desired; hut I prefer to form the muntins as `shown in Fig. 3, in which the parts 4 and 5 are made substantially the same shape in crosssection, and when assembled within a sash they `form the grooves 6 and 7 to receive the edge of the paneof glass 8 and the putty 9, in which` the glass is embedded to make an air-tight joint at. this place.

In forming a sash in accordance with my invention I construct the outer portion l of the desired dimensions. I form pieces of muntin slightly shorter than the length and width of the panes of glass to be used. These muntins may be cut perfectly square at the ends, or they may he formed with a slight miter at the ends, so that two ormore muntins in meet- 'ing will t more closely together.

In order to form a rigid joint between two of more muntins whichl meet, I provide the sash on opposite sides thereof with the clamping-pieces 10, which are made to fit upon the outside of the muntins, as shown, and which extend a short distan ce upon each muntin from the joint between them. These clamping-pieces are drawn firmly against the opposide sides` of the meeting ends of the muntins by means of the single screw or bolt l1, as shown in Figs. 2 and 5, or` by two or more screws l2, as shown in Fig. 6. These clamping-pieces may be made of metal and cast or stamped into shape, or they may be made of any other suitable material and in any other manner than by casting or stamping; but I prefer to form them from sheet metal and stamp or press them into shape, as they will thereby be made more perfect, uniform, strong, and light. These clamping-pieces when used with hollow muntins may be used alone, as shown in Fig. 5, or they maybe used in connection with an interior filling-piece 13, inserted into the meeting ends of the hollow muntins, as shown in Figs. 2 and 3, which filling-piece may be made solid or hollow, as desired, but which is preferably made hollow, as shown on the drawings. If so desired, the clamping-pieces at a number of the joints between the muntins may be joined together, forming a single piece, which will then have tubular portions to receive the ends of the muntins, and in such a case the bolt or screws 11 and 12 may be dispensed with, if so desired. The ends of the muntins are rigidly connected to the outer portions 1 of the sash, also by the clamping-pieces 14 14, placed upon the opposite sides of the sash at the meeting of the muntin and the outer portion of the sash. One portion of the clamping-pieces 14 iits against the surface of the muntin and extends a short distance upon said muntin back from the end of the same, while another portion of the clamping-pieces 14 extends upon the side of the outer portion of the sash and may be provided with projections 15, which enter perforations or recesses in the sides of the outer portion 1 of the sash. These clamping-pieces 14 are clamped firmly against the end of the muntin and the side of the outer portion of the sash by means of the screw 0r bolt 16 or by any suitable equivalent and wellknown fastening device.

By forming a sash in the manner above described it will be seen that a very strong, rigid,

and durable sash is formed, that any one or more of the muntins may be taken out and replaced when desired, that a broken pane of 4 panes of glass in a sash, may be easily and quickly increased or decreased if itis desired to have smaller or larger panes of glass in a sash than is already in the sash.

When the sash is made as illustrated in Figs. 1', 2, and 3, with the muntins divided longitudinally into two parts, it is especially easy to reset a broken pane of glass, as the clamping-pieces 10 at the four corners of the pane on one side of the sash only may be removed 'and then the parts of the muntins on that side of the sash only may be removed, leaving the entire surface of the pane of glass exposed and ready to be taken out.

When the several parts of the sash are made of metal, and more especially of sheet metal, rolled or stamped into the proper shape, I am thereby able to make a very convenient, cheap, effective, and strong fireproof sash, in which there will be nothing excepting the glass used Y which would burn or would crack by the heat.

Ystood that the same formation of a joint may be used in the corners of the outer portion or frame of the sash and, in fact, in the construction of window frames, doors, doorframes, and for similar constructions.

Having thus fully described the nature, construction, and the operation of my invention, I wish to secure by Letters Patent and claim- 1. In a window sash, muntins made in lengths substantially that of the dimensions of the pane of glass to be used in the sash, clamping-pieces placed upon the opposite sides of the sash at the meeting place of a plurality of muntins fitting the surface of the muntins and extending a short distance on each muntin from its meeting place with the other muntins, and means to hold the clamping-pieces firmly in place against the opposite sides of the sash and the'muntins in place. 2. In a window-sash, tubular muntins made in lengths substantially that of the dimensions of the pane of glass to be used in the sash,

clamping-pieces placed upon the opposite sides of the sash at the meeting` place of a plurality of muntins tting the surface of the muntins and extending a short distance on each muntin from its meeting place with the other muntins, filling-pieces inserted within the meeting ends of the tubular muntins, and means to hold the clamping-pieces firmly in place against the opposite sides of the sash and the muntins in place.

3. In a window-sash, the combination with the outer portion of the sash and a muntin having its end adjacent to the inner surface of the outer portion of the sash, of clampingpieces on opposite sides of the sash fitting the surfaces of the muntin and the outer portion of the sash and extending a short distance upon the surfaces of said muntin and outer portion of the sash, and means to hold the clamping-pieces firmly in place against the opposite sides of the sash and the muntin and outer portion of the sash in proper relative positions.

4. In a window-sash, muntins divided longitudinally into two pieces thereby forming a groove for the reception of the glass, combined with clamping-.pieces on the opposite sides of the sash at the meeting place of said muntin with another part of the sash, said clamping-pieces fitting the surface of said muntin and other part of the sash, and means to hold the clamping-pieces firmly against IOC IOC
